Privacy Policy

The School, SnowWind Ski School (operating entity: Yukikaze Co., Ltd.; operations manager: Ryokan Ijuin; registered address available on request; privacy contact: info@ykhokkaido.com), handles your personal data in accordance with the Act on the Protection of Personal Information (APPI). This policy covers both our website (www.ykhokkaido.com) and the “雪風 SnowWind” mobile application (Android / iOS, “the App”).

Data we collect

Website

Booking & contact details: name, email, contact info, the course and time slot booked.
Payment details: processed by Stripe; the School does not store your full card number.
Safety & emergency data: emergency contact, and the minimum health information needed for safety.

App

Location (precise) — collected only while you actively start a ride recording. Used on-device to compute your run track, turns and speed, and to replay them on 3D terrain. Recording runs as a foreground service (a notification is shown while recording); the App does not collect location in the background when you are not recording. Ride recordings are stored locally on your device; nothing is uploaded unless you sign in and explicitly use sync.
Microphone / voice — recorded only while you hold the AI assistant’s microphone button. Audio is sent to our server for speech recognition (Cloudflare Workers AI / Whisper); the recognized text is answered by an AI service (DeepSeek). Voice audio is not retained long-term; please avoid speaking sensitive personal data.
Account details — if you choose to sign in: email, display name and avatar via Google Sign-In or email, stored in Supabase.
Learning / usage progress — practice progress in the teaching module (synced to Supabase after sign-in for cross-device use).

Special Care-Required Personal Information (Health, etc.)

Medical history, physical or mental health, medication and similar details may constitute Special Care-Required Personal Information under the APPI. The School collects such information only to the minimum extent necessary for safety management, with your separate, explicit consent; this data is access-restricted, is never used for marketing or ad targeting, and is retained for a shorter period.

Purpose of use

To provide and manage bookings, collect payment, and send confirmations / notifications.
To provide App features: ride recording & replay, the AI assistant, snow conditions & pre-trip reports, progress sync.
Customer contact and after-sales service.

Third-party processors

Stripe — credit-card payment processing.
Supabase — member accounts and sign-in (Google login), progress sync.
Resend — transactional email (booking confirmations etc.).
Cloudflare — hosting, security, speech recognition (Workers AI / Whisper), and Turnstile bot verification (invisible mode). Turnstile data handling is governed by the Cloudflare Privacy Policy and its Turnstile Privacy Addendum.
DeepSeek — text generation for the AI assistant (receives only your typed or transcribed text plus necessary conversation context; never your account data or raw location).
Open-Meteo — weather / snow forecast source (requests carry resort coordinates only, never your personal data or own location).
Some providers (such as Stripe, Supabase, Cloudflare and DeepSeek) may process data outside Japan. Where this constitutes providing personal data to a third party in a foreign country, the School complies with the APPI — where required, providing information about the recipient country’s data-protection system and safeguards, and obtaining your consent.

Cookies

This site may use essential cookies for basic functionality; booking and payment flows are handled by the third parties above on their own domains.

Retention & your rights

Ride recordings live on your device; you can delete them in the App at any time, and uninstalling the App removes local data.
The School does not retain data indefinitely; data is deleted or anonymized once the purpose of use has been achieved and there is no legal, accounting, claims, dispute, or safety need to retain it. Health information is retained for a shorter period; incident/dispute records are preserved as required by law.
Under the law, you may request notification of the purpose of use, disclosure, correction, addition, deletion, suspension of use, or suspension of provision to third parties, regarding your personal data (the School may verify your identity to the extent permitted by law). Please email info@ykhokkaido.com; the School will respond within a reasonable period. For the account/data deletion request process, timeline, and retention exceptions, see the Account & Data Deletion page.

Policy Changes

If this policy changes materially, the effective date will be announced on this website; if a new purpose exceeds the scope of your original consent, the School will obtain your consent separately.
